Why can't connect to remote server in sublime text sftp plugin?

Question

linux

The config looks like this -

{
    // The tab key will cycle through the settings when first created
    // Visit http://wbond.net/sublime_packages/sftp/settings for help
    
    // sftp, ftp or ftps
    "type": "sftp",

    "save_before_upload": true,
    "upload_on_save": false,
    "sync_down_on_open": false,
    "sync_skip_deletes": false,
    "sync_same_age": true,
    "confirm_downloads": false,
    "confirm_sync": true,
    "confirm_overwrite_newer": false,
    
    "host": "host1.domain.ru",
    "user": "khvostov",
    //"password": "password",
    //"port": "22",
    
    "remote_path": "/home/khvostov",
    "ignore_regexes": [
        "\\.sublime-(project|workspace)", "sftp-config(-alt\\d?)?\\.json",
        "sftp-settings\\.json", "/venv/", "\\.svn/", "\\.hg/", "\\.git/",
        "\\.bzr", "_darcs", "CVS", "\\.DS_Store", "Thumbs\\.db", "desktop\\.ini"
    ],
    //"file_permissions": "664",
    //"dir_permissions": "775",
    
    //"extra_list_connections": 0,

    "connect_timeout": 30,
    //"keepalive": 120,
    //"ftp_passive_mode": true,
    //"ftp_obey_passive_host": false,
    "ssh_key_file": "C:\\Users\\khvostov\\.ssh\\khvostov23122014.ppk",
    //"sftp_flags": ["-F", "/path/to/ssh_config"],
    
    //"preserve_modification_times": false,
    //"remote_time_offset_in_hours": 0,
    //"remote_encoding": "utf-8",
    //"remote_locale": "C",
    //"allow_config_upload": false,
}

When trying to connect, it crashes with an error - Connecting to SFTP server "host1.domain.ru" as "khvostov" ........... failure (Connection timeout)
Although it comes through putty.
What could be the problem? Where to look on the host?
